Well I found the 177.39 and physx 8.06.12 driver this morning. It helps with the 3DMark Vantage benchmark but nothing else as far as I can see. Plus it didn't like any of my usual overclocks, hopefully it will be better optimized when it is offically released :-)

Here's my 3DMark Vantage score with the 175.16 drivers

15514 - ORB - Compare



And with the 177.39 + physX Driver

17695 - ORB - Compare



Edit:

Well I just got done trying out the Windows XP version of these drivers. The good news is , in XP I can run my system at 4 GHZ and OC my video and run 3DMark06 without any crashes or bsod. But they only provided a small boost in performance, 100 points. And I don't know if the PhysX driver was responsible or not. 3DMark06 does carry the PhysX Logo so I was really hoping it would help some. But it seems to be minimal at best. Once again, maybe when these are offically released the performance will improve.

With the 175.16 Drivers alone

With the 177.39 + PhysX 8.06.12 driver

Well the system isn't letting me post any pictures. I'll try updating my post later

I think Unreal Tournament 3 is the only game that will actually allow you to take advantage of graphic card accelerated PhysX at the moment. I seem to remember the initial effects being pretty lame---has that changed at all?

I downloaded the Physx mod pack for UT3 and was rather unimpressed. The frame rate was unplayable most of the time there were any physics effects on screen, and while physics definitely has a role in the future of gaming, it's much more of a gimmick right now.

It'd be cool if I could set one of the GPUs on my GX2 to handle physics, and the other to handle the graphics, but I don't know if that's even possible.

From what I've been reading, that is suppose to be one of the benefits. But as of right now it's not supported.
